This buffer along with a David Tubbs flat buffer spring helped with recoil of my AR. Really like the product.

Works well. Moved my spent shell ejection pattern from 2 o'clock to about 3:30. I don't notice much difference in recoil, not that there is much recoil on 5.56.

Lowers felt recoil on mid length. Primary Arms knows how to sell and ship. Will always give them a first look.

Great deal from Primary Arms. Haven't used the buffer yet, but appears top notch, and is obviously dead silent. Loved the price, shipping time, and service from Primary!!
